Vitamins are conventionally divided into the fat-soluble group A, D, E and K, and the water-soluble group, vitamin C (ascorbic acid) and the B vitamins-B 1 (thiamine), B 2 (riboflavine, riboflavin), nicotinic acid, B6 (pyridoxine), pantothenic acid, biotin, folic acid and B12.
Vitamins are organic compounds that are needed in small quantities to sustain life. Most vitamins need to come from food. This is because the human body either does not produce enough of them, or it does not produce any at all. Each organism has different vitamin requirements. For example, humans need to consume vitamin C, or ascorbic acid, but dogs do not.
